Hi All

I want to modify the below EEqn.H in order to add Arrhenius Reaction Rate to it. I am wondering whether I need to call it or add its equation separately to the file?

Current EEqn:

{
    volScalarField& he = thermo.he();

    fvScalarMatrix EEqn
    (
        fvm::ddt(rho, he) + mvConvection->fvmDiv(phi, he)
      + fvc::ddt(rho, K) + fvc::div(phi, K)
      + (
            he.name() == "e"
          ? fvc::div
            (
                fvc::absolute(phi/fvc::interpolate(rho), U),
                p,
                "div(phiv,p)"
            )
          : -dpdt
        )
      - fvm::laplacian(turbulence->alphaEff(), he)
//    - fvm::laplacian(turbulence->muEff(), he)  // unit lewis no.
     ==
        reaction->Sh()
      + fvOptions(rho, he)
    );

    EEqn.relax();

    fvOptions.constrain(EEqn);

    EEqn.solve();

    fvOptions.correct(he);

    thermo.correct();

    Info<< "min/max(T) = "
        << min(T).value() << ", " << max(T).value() << endl;
}

My energy equation should be like this:

 ∂(ρE)/∂t + ∂[u(ρE + p)]/∂x + ∂[v(ρE + p)]/∂y = 

∂(uσxx + vσxy − qx)/∂x + ∂(vσyy + uσyx − qy)/∂y + qω

where:

ω == Arrhenius Reaction Rate

Excuse me, have you added it successfully? I have also encountered the same problem. Could you please share it （leeseungnan@163.com）
